In Great Britain May 30, 1938 21 Claims.

This invention relates to typographical slug casting machines, such asthose known commercially under the registered trade mark Linotype,wherein composed lines of matrices and spacebands are sustained betweena pair of lineclamping jaws in front of a slotted mould in which atypebar or slug is cast, and wherein after the casting operation; eachline is removed from between the clamping jaws for delivery to distributing mechanism, and the cast slug is ejected from the mould afterthe latter has been removed from the casting position to the ejectingposition. 7

In such machines as usually constructed, the

i line clamping jaws are mounted in a vise frame which also carriesother mechanisms, such as the elevator or line' transporter andjustifying and quadding devices, the operations of which are controlledby cams on a shaft at the rear of the machine through levers extendingforwardly to connect with the respective mechanisms, on the Moreover,the vise frame ismounted to swing forwardly about a horizontal axis togive access to parts of-the machine located behind it, whichnecessitates detachable connections between certain of the saidmechanisms and levers.

The principal objects of the invention are to effect a simplification ofthe devices'for operating the vise frame mechanisms, and to providegreater freedom of acess to parts located at the rear of the vise frame.A furtherobject of the invention is to adapt the vise frame for use witha mould which is movable t0 and from a horizontal ejecting position, soas to provide free passage for the ejection of a'slug from the mould atthe rear of the vise frame to a galley at the front thereof.

With these objects in view, the invention contemplates an arrangement inwhich the operating levers for the vise frame mechanisms are mounted soas to be movable with the vise frame and are controlledfrom a cam shaftwhich is co-axial with the pivot of th said frame, The invention furthercontemplates the arrangement of the respective mechanisms on the viseframe soas to leave a central portion thereof free from obstructionsfrom front to rear.

One constructional form of apparatus according to the invention isillustrated, by way of example, in the accompanying drawings, in which:

Figure 1 is a front elevation of a vise frame and cam shaft according tothe invention;

Figure 2 is a front elevation of the vise frame and associated parts,drawn to a larger scale and partly broken away;

Figure 3 is a side elevation partly in section on the line 3-3 of Figure2, as viewed from the right of that figure;

Figure 4 is a plan view, partly in section, taken on the line 4- 3 ofFigure 2, and

Figure'5 is a diagram indicating different -set-' tings of the quaddercontrol devices.

According to the embodiment of the invention '19 illustrated in thedrawings, the vise frame I, shown in outline in Figure 1, is formed withlaterally extending brackets 2, 3 embracing a vertical cam shaft l. Thelower vise frame bracket 2 is supported on ball bearings in a memdicatedat 9 (Figure 1), or by other appropriate means, and it constitutes aself-contained unit comprising a line transporter, justifying mechanismand. quadding mechanism, with operating devices therefor, as hereinafterdescribed. The

The vise frame I is thus hinged cam shaft4 by which the said operatingdevices are controlled, is operativelyconnected to the main cam shaftI8, for example, by bevel gears I9, 20 and shaft 2|,see particularlyFigure 3. It will be understood that the cam shaft 98, in the presentarrangement, is similar to the main cam shaft of known machines, andcarries cams and gears arranged to control, in substantially the normalway,- the operation of organs of the machine other than those controlledby the cam shaft 4.

' The line transporter or elevator l0 (see Figure 1) is mounted in aslide II at the top of thevise frame I, in which slide the elevator canbe moved downwardly from the position shown in Figure 1, in which itreceives a composed matrix line from I which a slug is to be cast, tocasting position in which the line is sustained between clamping jawsl2, l3, mounted in the vise frame 1!; The movementsof the elevator IDare controlled by a cam l4 on the vertical shaft 4 through a lever l5and a spring-loaded link IS. The lever I5 is fulcrumed on a bracket H,the base of which surrounds the shaft 4 and is supported between I patein the pivotal movement of the vice frame I. It should be noted that theelevator It moves downwardly under the action of gravity when suchmovement is permitted by rotation of the cam M, and is positively movedupwardly by the action of the cam M on the lever l5, to return it to theposition shown in Figure 1, for the discharge of a line which has beencast and the reception of a succeeding line; the spring loading of thelink 16 permits yielding in the event of the upward movement of theelevator being obstructed.

The justifying mechanism employed in carrying out the inventionaccording to the present embodiment thereof, comprises, as is usual, ahorizontal justification bar 22 carried by two Vertical rods 23, 24slidable in guides at opposite sides of the vise frame, which bar isadapted to engage the depending slides of spacebands in the composedline when the latter is in casting position between the vise jaws l2,I3. In order to operate the justification rods 23, 24 under the controlof a cam 25 on the shaft 5, the said rods are connected together attheir lower ends by a bar 26 which is acted upon by rollers 21, 28 onthe two arms of a lever 29 fast on a rock shaft 30 extending across thevise frame I. The lefthand end of the rock shaft 30 (as viewed in Figure2) is extended through the vise frame and has fast on it an arm 38provided with a roller 32 held up to the face of the cam 25 by a spring33 acting between said arm and the vise frame. The spring 33 effects theoperative movement of the justification bar 22 through the connectionsjust described, and the cam 25 normally retains the bar in itsinoperative position (as shown in Figure 2) against the action of thespring.

For the purpose of automatically quadding or centering a short line, itis preferred to employ in conjunction with the present improvedviseframe, a modified form of the known type of quadding mechanismcomprising a pair of levers 34, 35 (Figure 2) connected by links 36, 31to the vise-jaw blocks 38, 39 respectively, and arranged for connectionto or disconnection from a vertically reciprocable rod by which thequadding movement of either or both of the jaws is effected. Suchmodified form, which permits the mechanism to be controlled by a cam Mon the shaft 1, and leaves the central portion of the vise frame I freefrom obstructions, will now be described.

According to the invention an operating rod is provided for each of thelevers as, 35, a rod ll being appropriate to the lever 34 connected withtheleft-hand vise jaw I2, and a rod 42 appropriate to the lever 35connected with the right- I hand vise jaw 13, said rods being disposedone at each side of the vise frame. The control rods are slidably androtatably mounted in guides 43, 44, and are connected together at theirlower ends by a transverse bar 45 relatively to which the rods are freeto rotate. The operative reciprocating movements of the rods 4|, 42, aretransmitted thereto through the bar 45. For this purpose the bar 45 isconnected by adjustable depending links 46 to arms l'l'of a lever memberfreely mounted on a transverse rock shaft 48, which lever member carriesa spring barrel 49 having a plunger 59 and is formed with a bridge-pieceThe shaft 18 has fast to it a lever arm 52 extending forwardly betweenthe bridge-piece 5i and the plunger 58, and a further arm 53 fast to itsleft-hand end, beyond the vise frame, carrying a roller 54 in engagementwith the cam 40. An adjusting screw 55 in the bridge-piece 5| bears onthe underside of the lever arm 52. These connections ensure that whenthe lever arm 53 is actuated by the cam 40 the arm 52 acts through thespring plunger 50 to move the control rods 4|, 42 upwardly. By suchupward movement the jaw-operating lever .or levers for the time beingconnected to one or both of the rods, is or are actuated to close therespective jaw or both jaws inwardly into contact with the composedline.

To enable the control rods 4|, 62 and jaw operating levers 34, 35, to beconnected and disconnected as desired, the lower arm of each lever isprovided with a projecting pin 56 adapted to be engaged by a groovedcollar 5'! the lower flange of which is mutilated, at the upper end ofeach control rod. The angular dispositions of the mutilated portions ofthe collar flanges, as will be understood by reference to Figure 5, aresuch that by simultaneous angular adjustment of the two rods, bothlevers may be disconnected for normal working (position A in Figure 5),or connected as shown at C for centering; the lever 34 only may beconnected for quadding with the left-hand jaw l2, which setting isindicated at B, orthe lever 35 only may be connected for quadding withthe right-hand jaw 13 as indicated at D in the said figure.

Angular adjustment of the rods is provided for, in the arrangementshown, by axially fixed gears 58 splined to the rods in engagement withracks 59 connected to a manually operable setting lever 60. The racks 59are carried, in relatively offset relationship, on a slide 6| at thefront of the vise frame, one of the racks being arranged to engage atthe front the gear appropriate to the rod 5| and the other rack disposedat the rear of the gear appropriate to the rod 42, as shown best inFigure 4, so that transverse adjustment of the slide 6| effects angularmovement of the gears in respectively opposite directions. A link 62connects the slide 6! with the lever 69 and the latter may be providedwith a detent device, such as a spring plunger 63 cooperating with holesin a plate 64 by which the position of the rack mechanism may bedetermined for each of the settings, in accordance with indications Reg,LIL, C. and RH. appearing on the plate 64 as shown in Figure 2.

With the above-described arrangements of the elevator, justifyingmechanism and quadding mechanism, the central portion of the vise frameis left clear, thus providing a construction particularly suitable foruse in a machine comprising a mould which is movable from castingposition to a horizontal ejecting position below the casting position.Moreover, the Vise frame with the associated mechanisms may be turnedoutwardly about the axis of the cam shaft, while the cam levers remainin contact with their operating cams, to give complete freedom of accessto the rear of the vise frame and to the machine parts located to therear thereof when it is in its operative position.

It is to be understood that the constructional forms of the devicesabove-described are given merely as examples of one convenientarrangement of mechanism according to the invention, and that a viseframe according to the invention may embody devices of variousconstructions operable from a cam shaft about the axis of which the viseframe with its associated devices is adjustable as a self-containedunit.
